Edit your /etc/X11/XF86Config-4. Find the InputDevice section for
the mouse. If you connect the mouse to your Thinkpad using a PS/2
socket (round, 6 pins), then a single InputDevice suffices for both the
TrackPoint and the external mouse.  If you connect the mouse to your
Thinkpad using a USB socket, then you need a separate section for the
USB mouse.  I assume you have one if necessary, because you say the
mouse is working fine as a two-button mouse.

In the appropriate InputDevice section, set the Protocol option to
"IMPS/2". Make sure the Emulate3Buttons option is not set - if it Set
the protocol to "IMPS/2". set. Set the ZAxisMapping option to "4 5".

Example for PS/2 mouse:

    Section "InputDevice"
	Identifier "Mouse0"
	Driver "mouse"

	# /dev/mouse should be a symlink to the appropriate device,
	# such as /dev/psaux
	Option "Device" "/dev/mouse"

	Option "Protocol" "IMPS/2"
	Option "ZAxisMapping" "4 5"
    EndSection


Example for USB mouse:

    Section "InputDevice"
	Identifier "Mouse1"
	Driver "mouse"

	Option "Device" "/dev/input/mice"

	Option "Protocol" "IMPS/2"
	Option "ZAxisMapping" "4 5"
    EndSection
